Specification of Letters Patent.

Patented Aug. 15, 1905.,

Application filed February 27, 1905. Serial No. 247,604,.

To It who/7t it may concern.-

Be it known that I, AN'roN Fooou, a subject 01 the Emperor ofAustria-llungary, residing at No. 90 fl lugengasse, Vienna,Austria-Hungary, have invented new and useful .lmprovements inRailway-(far Couplings, oi which the following is a specification.

This invention relates to an improved constructional Form of thearraiigement (protected by United States Patent No. 779,472) tortigl'itening the engaged coupling and. for automatically untighteningthe latter when disci'lgaged by means of an eccentric, in whicharrangement the movement of the eccentric which tightens the cou] )lingis el'lected by lever mechanism, whereby both parts are lirmly unitedand the automatic nntightening is caused by a weighted lever acting onthe shalt instead of by unreliable springs, as hereto tore, saidweighted lever being raised when tensioned and secured in this positionby a tumbler which is z'tutomatically released when disengaging thecoupling, and thus produces the automatic untightening.

Referring to the accompanying drawings, Figures 1 and 2 show theimproved tightening and iimtightening means in plan and elevation oil? acoupling, and Fig. 3 shows a part oi the same in front elevation.

According to the present invention the shaft 27 is lixed beneath thebutter-plate 19 and can be turned at will by the lever 39, Fig. l, whichis attached to the ends of the shaft and adapted to be placed beneaththe butter-plate 15) when not used. The shaft 2'? carries a two-armedlever d0 instead of the s n'ing-barrel and looped lever of United StatesPatent No. 779,472. The shorter arm of this lever 4L0 is connected by arod 41 to the eccentric-lever 18 ot' the eccentric 17, while the longerarm is weighted by a weight L2, Fig. 2, which replaces the spring of theknown construction. The hub of the lever 40 is provided with projections433, and a horizontal tumbler 45, Fig. 3, which is attached to thebufl'er-plate 19 and tensioned against the projections L33 by a spring 41, arranged above the projections in such a manner that when the lever4:0 is turned into the tightened position (indicated in Fig. 2 by dottedlines) the said tmnbler engages in one oi the projections :13, and thuslocks the lever 4:0 in the tightened position.

ilhc s n'ing-drum 20, adapted for the uncoupling and connected to theuncoupling-lever 12 by the chain 22, is loosely and rotatably mounted ona vertical pivot 46 (instead of being keyed to the horizontalcoupliiig-sha'lit, as heretofore,) and for the purpose ol uncoupling itcan be turned in the direction of the arrow by means of lever mechanism47 4-8, lixied beneath the larder-plate and shown in Fig. 1 in dottedlines. The s ning-drul'n 20 is provided on its periphery with a cam L9,in the path oli which the free end of the tumbler 45 projects, so thatwhen the drum 20 turns in the direction 01 the arrow, Fig. i, .into theuncoupling position the cam t?) lifts the tram blerif), which thusreleases the lever d0. The

latter turns under the action of the weight 42 into the position shownin Fig. 1, and thereby untightens the coupling.

.ltlaving now particularly described and ascertained the nature ol mysaid invention and in what manner the same is to be performed, .1declare that what l claim, and wish to secure by Letters Patent, is--.ln eccentric-actuated tightenii'lg and automati :ally-untighteningmeans :lor automatic railway-car couplings, the combination of a shaft,a two-armed lever mounted thereon, a weigl'lt on one end of said lever,an eccentric, a lever 18 connected thereto, a rod connecting the otherarm of the two-armed lever to said lever 18, projections on saidtwo-armed lever, a tumbler engaging with said projections to lock thetwo-armed lever against movement, a spring-drum having a cam on itsperiphery and means for rotating said drum to bring the cam inengagel'nent with the tumbler to unlock the parts, substantially.lescribed.

i n tcsti mony \vhereol I have signed my name to this s pecilicatlon 1nthe presence of two subscribing witnesses.

ANTON FODOR.
